Bet Types

A fixed binary is a bet where the binary price remains fixed but where the strike price (the price the market needs to reach for the event to occur and therefore make up at 100) is moving.

For example, if the bet is that "the £/$ will end up 25 by the end of the hour" the Buy and Sell prices would remain the same for the entire lifetime of the bet but the proposition might change to "the £/$ ending up 21", or "up 19", or "up 13", or "up 7", for example.

Clearly fixed binary and floating binary bets are opposites of each other. With fixed binaries the prices remain static whilst the target price moves. With floating binaries the prices move whilst the target price remains static.
